Cellular Smugglers: Laden nanoparticles hitch a ride on bacteria

By loading genes onto nanoparticles, then attaching the nanoparticles to bacteria, scientists have devised a new way of shuttling potentially therapeutic material into mammalian cells. Because the nanoparticles could carry a variety of molecular cargo, the system could have a wide range of applications, including cancer therapy and insertion of cellular biosensors.
